Step 1: Put your car in parking, open up and stabilise the hood

Safety is a priority, so make sure the car is parked and the emergency brake are engaged.

If possible, avoid changing your car battery if it is parked on an inclining slope. This is to ensure your car stays secure when you're working on the car battery. 

Once your car is ready, open up the vehicle’s hood and allow it to cool enough that you can work on the parts of your car hood without the risk of burning yourself.

One of the similarities of car batteries to your regular AA batteries is that they both have positive and negative ends.

Step 3: Detach the cables connected to the terminals

At this point, it's important to remove the negative/black cable first. You can use something like a wrench to loosen the nut holding the cable on the negative terminal of the battery. Next, detach other cable (red/positive) from the battery.

You should see several clamps holding the battery in place. Inspect them carefully and then remove them.

Once you set aside the clamps and fasteners, you should be able to remove the battery entirely. Be careful to keep your hands steady in order not to spill any chemicals from the battery.

Step 5: Clean the terminals and connector cables

You can utilize a wire brush or the rough surface of a sponge together with a battery cleaning solution to clean the battery tray and the cables. Then, proceed to dry them completely and thoroughly. Never install a car battery if there are any wet parts remaining!

Step 6: Insert the New Battery

You can then reinstall the clamps - connect the positive end (red or positive cable to the red or positive terminal) and tighten with a wrench. Next, do the same with the black or negative cable and terminal.

You should also double check your connections are secure by attempting to move it around - it shouldn't be shifting and it should feel tight and secure.
